In this study, it is aimed to develop a measurement tool with measurement validity and reliability, which can be utilized to identify the academic self-efficacy attitudes of faculty members working in the education faculty. The literature was screened during the development of the scale, the opinions of the teaching staff about the subject were…

There is a need for cancer-specific tools to evaluate loneliness and cancer-related negative social expectations before developing interventions for cancer patients. The purpose of this study was to examine the reliability and validity of the Cancer Loneliness and the Cancer-related Negative Social Expectations Scale. Data were collected from 300…

What follows is a practical guide for establishing the validity of a survey for research purposes. The motivation for providing this guide is our observation that researchers, not necessarily being survey researchers per se, but wanting to use a survey method, lack a concise resource on validity. There is far more to know about surveys and survey…

Purpose: The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method: We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were…

Many professionals use the handheld dynamometers (HHDs) to assess isometric strength. This study aimed to evaluate the validity, reliability, and sensitivity to change of a DiCI (a new HHD) for the strength measurement of knee and hip muscles and their ratios. Thirty-five recreational athletes completed quadriceps, hamstring, and hip adductors and…

When rating performance assessments, raters may ascribe different scores for the same performance when rubric application does not align with the intended application of the scoring criteria. Given performance assessment score interpretation assumes raters apply rubrics as rubric developers intended, misalignment between raters' scoring processes…

Being a significant dimension in affective behavior education, values are guiding concepts for explaining the cognitive and social structures. In the process of value acquisition, the tendency of individuals for the value being targeted for acquisition bears a great significance. In the present study, the main aim is to develop an assessment…

Purpose: The current intelligibility tests performed on speakers with atypical speech production are limited by the ability of listeners to restore distorted sequences. This results in a measure that is overvalued when compared with the real articulatory performance. In this article, we present a new intelligibility test in order to neutralize the…

Background/Context: The Race to the Top federal initiatives and requirements surrounding waivers of No Child Left Behind promoted expanded use of value-added models (VAMs) to evaluate teachers. Even after passage of the Every Student Succeeds Act (ESSA) relaxed these requirements, allowing more flexibility and local control, many states and…

The Modified Checklist for Autism in Toddlers-revised/follow-up (M-CHAT-R/F) was developed to reduce the number of cases requiring telephone verification. The aim of this study was to validate a Spanish version of the M-CHAT-R/F in the Spanish public health system. The M-CHAT-R/F was translated, culturally adapted, and then administered to 6625…

The purpose of this research was to develop and validate a new instrument, the Dynamic Career Scale (DCS), which measures four different modes of functioning in facing career failures and challenges (mania, envy, manic reparation, and true reparation) according to Klein's object relations theory. Two studies were respectively conducted on adult…

While participating as a mentor teacher in a professional development project, Alison Vickery, a middle school teacher, developed a strategy: claim-rule-connection (CRC). The "claim" was the answer or response to the question; the "rule" was the theorem, fact, or proof; and the "connection" was an explanation of how…
